Wideband Imaging Radars Summary Table (September 10, 2012)

The table below summarizes the main characteristics (where these are known or can be estimated) of the wide-band imaging radars in the Space Surveillance Network. See the posts on the individual systems for details. (Click on the Table for a more legible version)

This is supported somewhat by the image in Appendix B of the same collection showing Cosmos 2388 at approximately 35,000 km range, approximately geosynchronous altitude (though Cosmos 2388 itself is in a Molniya orbit).

Allen,
Thanks for your comment.
I completely agree. The P-A-G of GLobus II is probably about one-seventh that of Haystack, so it would take roughly seven times longer to produce a comparable image, but the integration times involved are already quite long, so in many cases that wouldn’t matter much. And thanks for the point about Cosmao 2388. I had seen this in your collection before, but had forgotten where I’d seen it.

Just a P.S., but it’s worth noting that if a satellite is truly geostationary (not just geosynchronous) and three-axis stabilized, range-doppler imaging (aka ISAR) isn’t possible from a fixed site on the Earth’s surface because there isn’t any doppler.
